quick 9920 question
 

Hey, I think the esc I have is a 9920, but it isnt marked. The 9920 is the only speed control with (4) capicitors on the side where the power from the batteries come in, right?




EDIT BY RENE/SERUM
the new 9920 has got 2 instead of 4 caps, safe yourself some reading and jump to the 3rd page.. :p

The 9920 i had only had 2 capacitors on the power input end.

I have 4, mine is a 9920 as marked:

So why do you have 2? Oh well, in theory more capacitors is better.

Mine deffinatly had 2, dunno why, as it was marked up as a 9920, maybe thats why it blew running a 7xl.

the 9920s mike sells claim to have 4 capacitors
maybe they use to make them with only 2 capacitors it is hard to tell

I doubt you would get a 9920 with 2 capacitors confused with 4.

How many does a 7720 have?

I only brought it a few weeks ago (2) so surely should of had 4 capacitors, unless it was marked incorrectly, and was a 7020 for example, then it would explain why it smoked using a 7xl.

Strange, yeh it should of had 4 capacitors.

Mike might be able to know more. Suprised BK would mark their own ESCs up wrong?

Well what ever it was it cost $205, and was marked up as a 9920, and smoked with a 7xl motor.

e-maxx-kid,
email mike something doesnt seem right maybe he has a few ideas about what is wrong with your 9920

Its been sent to Germany, but aint got a response from them as yet, but it appears it was a 7020 therefore could'nt handle the current draw, and smoked?

Sounds like it.The airplane 9920s only have 2 capacitors too i think.But basically,any of the car controllers,99A or above have 4 capacitors.

If you look at my sticker (image in quote below) why is the 9920 ticked in the WC (I think it says WC or WIC) bit and not Car?

It is marked car,that other 'X' is for 9920.

Yes it is marked as Car but not Car-9920. It is a 9920 of WC or whatever? Look, you will see 2 boxes both labeld 9920.

:o

It is marked car-9920,the sticker is the same for any warrior,so they just tick the 2 boxes which correspond to that controller,so that means it's a car 9920.

This is an old thing, but maybe it has something to do with your case:

Altough Mike knows what he sends away, I'm sure.

A 99amp Warrior can handle a 7xl just fine. But of course you can push it with gearing.

WC stand for water cooling, I believe.

Nick,i see what you mean now,the stickers do have 9920 twice on them.Mine has the same boxes ticked as yours.You'd know if it wasn't a car.'cause it wouldn't work.And it would only have 2 capacitors.

it was 66/20, and just fried during use.

There's a 6620? 7020 surely.Are they sending you a replacement?

There's a 15020 warrior now aswell.

I aint heard from them as of yet,

WC = water cooling? How does that work or feature?

I think he meant 66/20 gearing :L:.

Isn't that gearing a little high for an E-Maxx?

Oh yeah,Doh!:L:

Now I'm worried. I just bought a 9920 from Mike its marked car 9920 but it only has 2 capacitors. What should I do?

Hmmm,the plot thickens.Contact Mike,find out what's going on.

Well I just sent Mike a PM I guess I'll have to wait and see what he says now. I'll post as soon as I hear from him.

It's for the boat guys. The heatsink would have some tubings.

I'm sure Mike will respond to this cap question.

20 pinion 66 on the spur, 4u2nv were in the same boat except mines already smoked up, this gives proof that a few are being marked up wrong.

I run 20/66 on 14 cells with a 9920 and 7XL. No problems, doesn't even get hot.

My 9920 has 4 caps'. So I guess there are 2 versions of the 9920 or are they just 7720s?

Just got a response to the e-mail from mike, the new 9920 have 2 capacitors, instead of 4.

Huh? So what is mine and why does it have 4?

4 should be better, that makes no sense.

is it just 2 larger cap? my 7020 has 2 and my 9920 has 4. strange why they would change it.

The new ones have double the capacity of the old ones, hence 2 of them.

Then yours is a 9920. :rolleyes:

yep a broken one at that.

another way to tell if its a 9920 is the 9920 is thicker because it has 2 circuit boards.

The first two pages of this thread scared the life out of me! I just got my 9920 a couple of days ago (havnt gotten to run it yet) and it only has 2 caps. Definitely breathed a big sigh of relief once I clicked the third page of this thread!

LOL roost..

I will edit the opening post.
